Within the world that we live in, we know three dimensions that apply to space, which are up-down, wast-west, and north-south, which are our form of directions as in where to be, to go, and other things of that nature. However there are the Fourth and Fifth Dimension that also exist within our space.

The Fourth Dimension is considered as Time. Thou we can move freely within west, east, north, and south, along with moving up and down, we can't move within time freely but only go forward in time. Physicists experimented with spacetime and discovered that both space and time are unified in different ways. They discover that as we look out into the sky, we look backwards in time due to how long it takes for light to reach us here on Earth's surface.

The Fifth Dimension also known at the Outback, is a space that is perpendicular to our dimension or brane. In the film, it is viewed as a viewpoint into physical manifestations of time where it can be interacted with. As where Cooper was able to change some events and cause the saving of humanity by messing around with stuff in his daughter's bedroom, eventually finding out how to give her the equation to figure out gravity. The way to the fifth dimension as seen by Cooper, was that "We brought ourselves here", meaning he thinks that not in his lifetime will this be created or movable with, as we to this day are still trying to figure out time travel, so we can travel freely in time, but at the moment can only travel in 3 dimensions to this day.

However there is more than just five dimension, but the fifth dimension is actually about 6 more, but for the sake of the movie, 6 is too many, and the decided to make it only the fifth dimension.

For this Monday, Nov. 9, we watched Star Trek from 2009. For today, I have two things that I'll be talking about, which is the physics of Warp Drives, and of Phaser Banks.

As most people know is that Warp Drives are used not only in Star Trek, but also other movies like Star Wars (Punch it, Chewy!), Space Balls (Ludicrous Speed!), and other sci fi movies that need a way to travel to other star systems with out having to deal with years of interstellar travel. How wrap drives work are allowing spaceships to travel in factors of the speed of light!

Wrap Factors (WF) is taking the number of the WF to the power of 3 times the speed of light.

So for example if I'm going to go at WF 5, that would be 5x5x5 = 125 x C = 37,474,057,250 m/s as our Final Velocity, which if we were headed to travel across the Milky Way, would take us 800 years.

So with Warp, it allows starships to travel long distances to other star systems in minutes instead of years! Imagine if Spock going 2,000,000 Light Year to the Andromeda system at Warp 5, he would be over 16,000 years old, turned into space dust along with a extremely rusted star ship. Warp is just another way to lessen movie times if you think about it. Another thing about Warp Drive, is Inertial Dampeners, but thats another thing that is used to reduce the effect of inertia caused by accelerating light speed and decelerating from light speed. Without it, I believe that the crew of the USS Enterprise and every other ship would be dead.

Now on Phaser Banks! So as for Phaser Banks, of course with ships of any kind (depending) needs some form of defense, like how Pirate ships back when boats were still wooden would use cannons that fired cannonballs, starships use Phaser Banks! Which is phaser based weapons that are mounted on starships like the Enterprise, that use particles. As according to Phil Plaits' Bad Astronomy, you can NOT see lasers coming at you, because the weapons are considered as light, so they travel at the speed of light, and that beams of photons would need a medium in space to be able to view them. So as them being involved in Star Trek, it would render space battles and action to be completely boring except when a random explosion shows up on the ship that gets hit from something. Pretty boring if it was just explosions... sounds like a Micheal Bay movie.

In Fat Man and Little Boy, we take a view into the background behind the creation of the two atomic bombs that were used in Hiroshima and Nagasaki. The scientists in the film were more dealt with stress of making this weapon instead of the consequences that would come from it. As the bomb came closer and closer the scientists began to split and separate their views on the project at hand. They took sides either to complete the bomb and put it to use, or to not finish it (or at least demonstrate it and have it not approved). Even after Louis Slotin, a scientist working on the project was exposed to radiation, the project was still underway and completed. Louis later died from radiation syndrome nine days later.

For me, if I was made to research into weapon applications, I would automatically refuse as I would rather find a more helpful way to incorporate my discoveries. Even if it was my only option in the career of science, I'd rather have my research benefit mankind for the years to come instead of causing many deaths to happen.

With the use of fossil fuels in everyday machinery being used constantly, we produce carbon dioxide that pollutes the air. Humans are a direct cause of global warming. We've caused climate change that has increased Earth's temperature by 1.5 degrees Fahrenheit and is expected to rise between 0.5 to 8.6 degrees in the next hundred years. Climate change doesn't just affect the Earth but everyone and everything on it. Animal migration, food supply, energy, and the environment can be affected by the climate. An example is from "The Day After Tomorrow": due to increased heat caused by greenhouse gas emissions, the natural weather patterns of the Earth shifted. This resulted in cooling by altering wind patterns. In the movie, this climatic shift caused massive bird migrations.

Fossil fuels are a constant resource that humans use for transportation, electricity, and factory production. Most people commute in cars, which use gasoline (a fossil fuel). carbon emissions from the cars pollute the air. `this polltion is Also known as greenhouse gases, which absorb radiation and heat up the Earth causing global warming.

As shown in the chart above, the temperature of the Earth has risen over the past 95 years when the Earth was balanced at around 0 increase. Humans are the cause of this increase in temperature and will continue in the coming years if greenhouse gases continue to be produced.
